Thanks Ed,
That works perfectly. I use that perl script to extract and separate search
strings into multiple field names and their corresponding search values, the
example above has been simplified down to just one field.
However, if you are aware of a better solution I'd love to know about it. I
initially found this post
(http://www.icdevgroup.org/pipermail/interchange-users/2002-September/025939
.html) which refers to a 'Search reference capability', but I couldn't find
any further info?
